All of TomTom's most recent new technologies are in evidence, too. The IQ Routes system is used when calculating journeys, so historic road speeds and traffic black spots are taken into account. This provides a much more accurate estimate of travel times.
The voice command and control introduced with the x40 series is built in, so you can operate the sat-nav verbally, although this is still not as comprehensive a system as that offered by Garmin's nuvi 860. The 950 also includes Enhanced Positioning Technology, which keeps your position updated more accurately in tunnels.
We haven't yet talked about the map and navigational performance of the 950. But almost nothing has changed here since the previous generation. The maps are clear and functional, with comprehensive journey information along the bottom. Full-screen lane guidance graphics pop up at complex motorway intersections. The only significant enhancement here is to the built-in speaker, which provides clearer audio than previous GOs.
As we predicted at the beginning of this review, the GO x50 LIVE series isn't going to change the world of sat-navs in the same way as its predecessor. So if you've already invested in a GO x40 LIVE, the new features shouldn't have you green with envy. If you're an infrequent traveller, the monthly subscription for LIVE means it remains an expensive option. However, TomTom has significantly reduced the unit price of the device itself, with the GO 950 LIVE being introduced for the same £299.99 as the GO 540 LIVE was a year ago. So if you do regularly drive long distances and are looking for a premium sat-nav to smooth your journeys, the TomTom GO x50 LIVE series should be top of your list.
